Influence sentence's length on translate result

Good day.

I try to understand how sentence’s length in array of sentence influence to translate.
For example: sentence in source array go to train in simple order: first, second, third and e.t.c. But if we put sentence to train in depends by them length: first - small sentence (2-3 words), second - medium sentence (4-7 words), third - long sentence (8-20 words). Will be result different?
